Precision machines with grinding head, cartridge-type spindle. Featuring MPG, HMI touch screen, and one-piece heady-duty casting bed.
Machine Structure
- Fixed work table with X/Z-axis servo-driven grinding head for high load stability and consistent accuracy
- Compact footprint with approximately 30% floor space saving compared to traditional table-travel machines
- One-piece heavy-duty casting bed with integrated carriage structure for maximum rigidity and vibration absorption
- Cross-feed system using precision linear guideways and AC servo motor with ball screw drive
- Tailstock quill with 70mm travel, tension spring return, and handwheel screw feed
Grinding Head
- High-precision cartridge-type spindle with angular contact bearings – rigid, accurate, and maintenance-free
- Cross feed with AC servo and ball screw for smooth and responsive positioning
Control Panel
- Equipped with MPG (manual pulse generator) for precise manual adjustments
- Ergonomic layout of controls for wheel head, table, and work head
- Safety interlocks and emergency stop functions for operator protection
HMI Touch Screen
- Color touchscreen HMI with intuitive operation and real-time status display
- Built-in multi-step grinding menus reduce programming complexity
- Support for manual, rapid, and automatic feed modes with parameter entry
